sane-teco3(5) SANE Scanner Access Now Easy sane-teco3(5)
NAME
sane-teco3 - SANE backend for TECO / RELISYS scanners
DESCRIPTION
The sane-teco3 library implements a SANE (Scanner Access Now Easy) back-
end that provides access to some TECO SCSI flatbed scanners. This back-
end should be considered alpha-quality software! TECO scanners are sold
under various brands like RELYSIS, PIOTECH, TRUST. This backend may or
may not support yours.
The scanners that should work with this backend are:
Vendor Model TECO model status
--------------------------- ---------- ----------
Relisys Scorpio VM3552 tested
Plustek OpticPro 2400SP VM3552 untested
PIOTECH Splendeur 3024 VM3552 tested
Trust Imagery 2400 SP VM3552 tested
Trust Imagery 4800 SP+ VM3552 tested
Trust Imagery 9600 SP VM3552 untested
The TECO VM number can usually be found at the back of the scanner. It
is also part of the FCC ID.
The options the backend supports can either be selected through command
line options to programs like scanimage(1) or through GUI elements in
xscanimage(1) or xsane(1).
If you have any success with a scanner not listed here, or if you notice
any strange behavior, please report to the backend maintainer or to the
SANE mailing list.
OPTIONS
Valid command line options and their syntax can be listed by using:
scanimage --help -d teco3
Scan Mode
--mode Black & White|Grayscale|Color
Selects the basic mode of operation of the scanner. The Black &
White mode is black and white only (1 bit). Grayscale will pro-
duce 256 levels of gray (8 bits). Color will produce a 24-bit
color image.
--resolution 1..1200
Selects the resolution for a scan. The scanner can do all resolu-
tions between 1 and 1200, in increments of 1.
--preview
Requests a preview scan. The resolution used for that scan is 22
dpi and the scan area is the maximum allowed. The scan mode is
user selected. The default is "no".
Geometry options
-l -t -x -y
Control the scan area: -l sets the top left x coordinate, -t the
top left y coordinate, -x selects the width and -y the height of
the scan area. All parameters are specified in millimeters by
default.
OPTIONS FOR COLOR MODE ONLY
--custom-gamma
Allows the user to specify a gamma table (see the next 3 parame-
ters).
--red-gamma-table
Can be used to download a user defined gamma table for the red
channel. The table must be 1024 bytes long.
--green-gamma-table
Can be used to download a user defined gamma table for the green
channel. The table must be 1024 bytes long.
--blue-gamma-table
Can be used to download a user defined gamma table for the blue
channel. The table must be 1024 bytes long.
CONFIGURATION FILE
The configuration file /etc/sane.d/teco3.conf supports only one item:
the device name to use (eg /dev/scanner).
FILES
/usr/lib/x86_64-linux-gnu/sane/libsane-teco3.a
The static library implementing this backend.
/usr/lib/x86_64-linux-gnu/sane/libsane-teco3.so
The shared library implementing this backend (present on systems
that support dynamic loading).
ENVIRONMENT
SANE_DEBUG_TECO3
If the library was compiled with debug support enabled, this en-
vironment variable controls the debug level for this backend.
E.g., a value of 128 requests all debug output to be printed.
Smaller levels reduce verbosity.
LIMITATIONS
The windows TWAIN driver has many more options than this SANE backend.
However they are only software adjustments. This backend only implements
what the scanner can support.
BUGS
Not much.
